If you deactivate your Facebook account, your timeline disappears from the Facebook service immediately. People on Facebook won't be able to search for you, though some info, like messages you sent, may still be visible to others. facebook also save your timeline information (ex: friends, photos, interests, etc.) in case you want to come back.

If you don't think you'll use Facebook again, you can request to have your account permanently deleted. Please keep in mind that you won't be able to reactivate your account or retrieve anything you've added. Before you do this, you may want to download a copy of your info from Facebook.
